I am getting an error with Google's structured data testing tool across all product pages.
"Aggregate Rating, ItemReviewed, A value for the itemReviewed field is required."
I am using JudgeMe with Shopify.
For example, for the URL - https://gamefishltd.co.uk/collections/single-handed-fly-rods/products/greys-gr70-streamflex-rods
I get this:
I have disabled microdata, on our SEO settings. So now the aggregate rating error that you had is no loger showing up
You can now have Google re-crawl on your store, so your reviews show up on Google search results.
If you need help with that, you can refer to this link:
